with disney it would be a plus if he could sing.. the only real life disney stars that aren't musically inclined are zach and cody from the hotel thing.. but they starred in a hit movie as very young boys.. so... find a musically talent..

The first step would be to show that he is good on camera, so make the highest-quality recording of his performance that you can. You should post the video on YouTube to see how appealing it is to the public, and if it goes over well, this is your "in". Best to have an agent to make contact with Disney.
